Automatic placement of objects in Dia

["Anthony Reina" <areina faculty ed umuc edu>]

I've been using a program called postgresql_autodoc 
(http://www.rbt.ca/autodoc/index.html) which creates database diagrams 
that are outputted to Dia format. Unfortunately, all of the boxes for 
the different database tables appear overtop of one another in Dia. Is 
there a command in Dia that I could add to automatically place the boxes 
so that they don't overlap?

Thanks.
